Oracle memory allocation in Linux

I am installing Oracle applications on Linux and they are taking 6-7 hours. I am using vmware and my guest OS is oracle enterprise Linux version 5 update 2. I have 8 Gigs of ram allocated to the vmware image but I think it is not being utilized at all. I can see only 88kd of swap space being used. What changes do I need to make to linux and oracle database to make the installs run faster? What linux commands can I use to see what memory oracle is using. I used 'top' and it seemed like oracle user never used more then 1 gig. I could see this from the system monitor.
Thanks in advance..

Using Linux with 8 GB needs some changes in the kernel. Metalink and Linux sites will help you.
I am not sure vmware is the virtualization you should use. We know that Oracle do not support installations

Network Monitoring is essential to ensure that computer systems and network devices are running. Use PRTG to monitor LANs, servers, websites, applications and devices, bandwidth, virtual environments, remote systems, IoT, and many more. PRTG is easy to set up & use.

I am not sure vmware is the virtualization you should use. We know that Oracle do not support installations under vmware. Possibly you can also try to install without vmware.

In the run time Linux is used almost all free RAM to cache there processes and disk blocks.
You have to use some tool to show the distribution of the memory.
In Novel I used 'osview'. Possibly there are such tool in the distribution you use.

Checking the Alert Log in AWS RDS Oracle can be a pain through their user interface. I made a script to download the Alert Log, look for errors, and email me the trace files. In this article I'll describe what I did and share my script.
